Support for the LDP, sanseito and conservitive ideas is mostly within the youth in japan https://mainichi.jp/articles/20251026/k00/00m/010/303000c

日本共産党 is notoriously an old people thing. If you just search this term on Japanese websites youll find tons of people saying the usual anti communist bullshit +Japanese. When the election happened I saw a couple that were "日本共産党は日本の敵です" "The communist part is the enemy of the people" It had a picture of a pamphlet from them that simply acknowledged US aggression and called for lessening japans reliance on them. It also called for a higher tax on the rich. and "こいつらを逮捕できないのは何かのバグだろ…" "It's a (programming) bug that we cant arrest these guys" There was even one I'm not sure how it was worded that called for 京都 Kyoto to be burned because its "where all the communists are" even though i think southern Tokyo was a hotspot

Not to say all older people do, its just their usual crowd is older because they've become less effective at actually reaching people over the years and their supporters have simply aged...that being said they can still be reactionary. There was a street interview I saw where a lady was in support of the communist party but was considering going with Sanseito because she hated what "chinese and indians were doing to japan" and that "white people were okay"

Its just Western/Imperial propoganda rotting the minds and a really ineffective incompetent left party. Which lets be real is basically just liberal, the actual revolutionaries branched off and arent in the party.

Also Takaichi is just seen as cool, she had a lotta hobbies before like being in a band, liking metal, riding a bike, she's just a cult of personality and pulled with it. Talking about politics is frowned upon by older generations but most younger ppl dont care about many traditions. It's just a theory, but I wouldn't be surprised if this helped her gain notoriety because people just talk about the cool stuff rather than the political stuff.
